arch top epi

Hi I own an epiphone by gibson archtop. I think it is the earliest one I have seen here, the serial number is 6013779, January 86.It is tobacco sunburst and very clean. Will try to post pics but have been trying for ages to join this forum without much luck.Has anyone got an earlier one than this? Also, the headstock lettering is different than I have seen anywhere else. It would seem that it was changed soon after production began.
